One pound of uncooked long-grain white rice is about 2 1/2 US cups. That pound of dry rice cooks into roughly 7 to 8 cups of cooked rice — enough for about 7 main-dish servings or 12 to 14 side servings, depending on how you plate it.

That "about" is doing real work. Rice grains vary, measuring cups vary, and the number changes the moment you switch from a US measuring cup to the little cup that came with your rice cooker. This page gives you the number that matters for shopping, the number that matters for cooking, and the one trap that makes both numbers lie.

Why a pound of rice isn't a whole number of cups

A US legal cup holds 240 ml, and a level cup of uncooked white rice weighs about 180 to 185 grams. A pound is 453.6 grams. Divide one by the other:

Dividing 453.6 by 185 gives 2.45 cups; dividing by 180 gives 2.52 cups.

So a standard pound bag lands between 2.4 and 2.5 US cups. Most recipe writers round that to "2 1/2 cups per pound," and you'll see 2.25 to 2.5 quoted on bag labels and conversion charts. The spread exists because rice settles differently in the cup — a freshly poured cup packs differently than one that has been sitting in a jar for a week.

Grain by grain: cups per pound by rice variety

Not every rice weighs the same in a cup. Long grains sit loosely; short, round grains pack tighter. The table below gives the typical range per US cup and what that means for one pound.

Brown rice sits in the same range as white even though the grains look bulkier, because the bran layer adds weight per grain. Basmati is the outlier on the high side: its grains are long and slender, so they fill a cup with fewer grams, and one pound stretches to nearly 2.7 cups.

The trap: rice-cooker cups are not US cups

The measuring cup that ships with a rice cooker holds about 180 ml — roughly three-quarters of a 240 ml US cup. A full rice-cooker cup of dry white rice weighs about 150 grams, not 180.

Run the same division with that cup and one pound of rice changes shape:

Dividing 453.6 by 150 gives 3.0 rice-cooker cups per pound.

That is the hidden jump. A recipe that says "one cup of rice" usually means a US measuring cup, but a rice cooker's marked line treats its own small cup as the unit. If you cook by the cooker's lines and shop by the pound, remember that a pound of rice is about 2.5 US cups but 3 cooker cups. Mismatch the two and you will boil over, under-water, or simply cook more than you planned.

From dry to cooked: what one pound feeds

Dry rice roughly triples in volume when it cooks. A quarter cup of dry long-grain rice becomes about three-quarters of a cup cooked; scale that up and 2.5 cups of dry rice become roughly 7.5 cups cooked.

Servings follow the cooked volume, not the dry:

Those counts assume you plate one cup of cooked rice for a main and half to three-quarters for a side. The USDA and most dietitian portion guides treat a half-cup of cooked rice as a standard serving; many restaurant recipes push toward a full cup. Your household sits somewhere between those two, which is why the table gives a range instead of a single number.

Shopping math: turning bag sizes into cups

This is the conversion you actually use in the aisle. Read the bag, convert to cups, then convert to cooked servings.

The pattern is worth noticing: every pound of rice adds about 2.5 cups dry and about 7.5 cups cooked. Once you lock that in, any bag size becomes mental arithmetic rather than a lookup.

Storing rice by the bucket: the same math at 25 lb

Preppers buy rice in 5-gallon buckets, and each bucket holds about 25 lb of white rice. At 2.5 cups per pound, that is roughly 63 cups of dry rice per bucket — about 188 cups cooked. The cup math scales cleanly all the way up; nothing about the pound-to-cup ratio changes with a bigger container, only the handling.

Frequently asked questions

Is a pound of brown rice more cups than a pound of white rice?

Not meaningfully. Brown rice weighs about 2.4 to 2.6 cups per pound, nearly identical to white, because the bran adds weight per grain while the grains are similar in shape.

Do I weigh rice or measure it?

Weighing is more repeatable: a scale removes the packing problem entirely. If a recipe gives grams, use grams. If it gives cups, use a US measuring cup and the 180-gram-per-cup figure above.

The recipe says "one cup." Which cup?

Assume a US measuring cup unless the recipe is written for a rice cooker. If your cooker has marked lines and you want the recipe's volume, measure with a US cup and pour that into the cooker bowl, then follow the water line for the corresponding number of cooker cups — the total volume, not the units, is what matters.

One pound of dry rice looks small. Is that really seven servings?

It does look small in the bag. Then it triples. Set 2.5 cups of dry rice next to the 7.5 cups it produces and the same volume fills a large serving bowl — which is why a pound bag that looks like a snack feeds a family dinner.

How much water do I add to a pound of rice?

Work from cups, not pounds: 1.5 to 2 parts water to 1 part dry rice for stovetop white rice, about 1.5 parts for a rice cooker. Since a pound is 2.5 cups, a pound of stovetop white rice wants roughly 3.75 to 5 cups of water.

The number to remember

Keep this one count in your head and every other figure on this page falls out of it: a pound of rice is two and a half US cups dry, and it triples when it cooks. Read a bag by pounds and think in cups; measure with the cup you actually cook with, whether that is a US cup or a cooker cup; and let the cooked volume — not the dry one — decide how many people it feeds. That single habit replaces every lookup table, and it never depends on which rice you bought.
